Why didnt other scientist immediantly accept the theory of uniformitarianiasm?

Uniformitarianism, the idea that geological processes operate at the same rates and in the same ways as they do today, faced skepticism because it challenged the prevailing belief in catastrophism, which emphasized sudden, dramatic events shaping the Earth. Many scientists were reluctant to accept this new perspective due to the lack of empirical evidence and the deeply ingrained views of Earth's history. Additionally, the concept required a significant shift in thinking about time scales, as it suggested that geological changes occur over vast periods, which was difficult for many to grasp at the time.
